IContainerControl.ActivateControl(Control) IContainerControl.ActivateControl(Control) IContainerControl.ActivateControl(Control) IContainerControl.ActivateControl(Control) Method

정의

지정된 컨트롤을 활성화합니다.Activates a specified control.

public:
 bool ActivateControl(System::Windows::Forms::Control ^ active);
public bool ActivateControl (System.Windows.Forms.Control active);
abstract member ActivateControl : System.Windows.Forms.Control -> bool
Public Function ActivateControl (active As Control) As Boolean

매개 변수

active
Control Control Control Control

활성화된 Control입니다.The Control being activated.

반환

컨트롤이 제대로 활성화되면 true이고, 그렇지 않으면 false입니다.true if the control is successfully activated; otherwise, false.

예제

다음 예제에서 상속 되는 ScrollableControl 클래스 및 구현을 IContainerControl 인터페이스입니다.The following example inherits from the ScrollableControl class and implements the IContainerControl interface. 구현에 추가 되는 ActiveControl 속성 및 ActivateControl 메서드.Implementation is added to the ActiveControl property and the ActivateControl method.

using namespace System;
using namespace System::Windows::Forms;
using namespace System::Drawing;

public ref class MyContainer: public ScrollableControl, public IContainerControl
{
private:
   Control^ activeControl;

public:
   MyContainer()
   {
      // Make the container control Blue so it can be distinguished on the form.
      this->BackColor = Color::Blue;

      // Make the container scrollable.
      this->AutoScroll = true;
   }

   property Control^ ActiveControl 
   {
      // Add implementation to the IContainerControl.ActiveControl property.
      virtual Control^ get()
      {
         return activeControl;
      }

      virtual void set( Control^ value )
      {
         
         // Make sure the control is a member of the ControlCollection.

구현자 참고

클래스에서 구현 되는 경우이 메서드는 지정 Control된를 활성화 합니다.When implemented in a class, this method activates the specified Control. 컨트롤은 컨테이너 컨트롤의 자식 이어야 합니다.The control must be a child of the container control.
